Description (last modified by )
/etc/mtab is no longer being referenced in Util-linux-2.27.1, Systemd-228, and future GLIBC releases.
So far it has been appropriate to have /etc/mtab as a link to /proc/self/mounts.
We should be able to remove the creation of mtab altogether in the future.

The only changes we would really need to the book would be:
- Add this command to the instructions for Glibc, both in cross-tools and final-system:
sed -i 's@/etc/mtab@/proc/mounts@' sysdeps/unix/sysv/linux/paths.h
- Remove the create of /etc/mtab from the Essential Symlinks page in the Boot and Chroot sections.
Disabling the creation of /etc/mtab in tmpfiles.d/etc.conf is optional - we could just go ahead and allow systemd to continue to create it, just in case something might use it.
I'm currently running a system without /etc/mtab, with only a couple differences.
Before configure on Glibc:
After make on systemd:
Haven't tried every testsuite, but the system does build and run without problems. I assume the change to Glibc should be unneeded once the next version is released. The change to systemd isn't really necessary, as it just prevents it from automatically creating an /etc/mtab link.
